Maple worksheets
-
Plotting Graphs: One of the primary uses of the computer will
be to give visualization. This worksheet gives syntax for plotting
graphs. The worksheet does not use
the calculus. Rather, it is an introduction to techniques for
plotting graphs with Maple.
-
Interpreting Graphs: The goal of this worksheet is to
understand the graph of the following function: >
h:=x->(x^3+3*x-5)/(x^2+2); Although you can just plot it in Maple,
we want to do this systematically to get a better idea what to look
for when looking at the graph. Read each question, and try to see if
you could have guessed this by looking at the graph of the
function.

Java Projects
-
Plotting lines: This
Java project(external link) can plot lines but it requires axes
fixed at the center of the window and do not represent any values of
x or y.
-
Spreadsheet Applications
-
Plotting straight lines: A spreadsheet can be used to plot a
graph of a straight line. Here is the HOW-TO
documentation with examples.
-
Finding Intersection of lines: This spreadsheet gives
the detail how to use spreadsheet to find the intersection of
lines.
